This really is trivial but it is a little off-putting. It doesn't help that just about all of the vehicles have the same interior main color. Here are some of the worse offenders.
MSE-3 Marid
IFV-6 Panther
M2 Slammer
This does affect the other vehicles as well to varying extents. It would be as "simple" as changing the colors in the texture files
Hello.
I am afraid that these old passenger interiors will not be edited to match the current new ones. There is a couple of reasons for this. First, we wanted to focus on the missing interiors that weren't in the game yet. Second, we wanted backward compatibility with our mod makers / community that might have changed them to their liking and third it would be much more time consuming as it might seem.
